MACHINE FOR MAKING BARBED-WIREI ENCING.

SPECIFICATION forming part of Letters Patent No. 254,516, dated March '7, 1882.

Application filed August 25, 1881. (No model.)

- Toall whom it may concern:

Be it known that we, SALMON THOMPSON and WILLIAM E. FARRELL, of Masonville, in

the county of Delaware and State of Iowa, have invented an Improvement in Machines for Making' Barbed-Wire Fencing, of which the following is a specification.

' The nature of this invention relates to certain new and useful improvements in the construction of machines to be employed in the manufacture of barbed-wire fencing, the object being to provide a machine which will secure the barbs upon the wire at stated intervals and form a burr or stud upon each side of the barb in the one passage of the wire through the machine.

The invention consists, first, in the peculiar arrangement of gears employed in the operative parts of the machine; second, in the peculiar device whereby the barbs are separated; third,in the peculiar construction of the guidewheels which embrace the wire and barb and hold the same while being operated upon by the burring-knife and hammer; fourth, in the peculiar construction, arrangement, and various combinations of the-parts, all as more fully hereinafter set forth.

Figure I is a perspective view of my improved machine. Fig. 2 is an enlarged perspective of a section of wire with the barb in place and as formed by my machine. Fig. 3 is a vertical cross-section on the line 3 y in Fig. 1. Fig. 4. is an enlarged perspective and a sectional view of the device employed for separating the barbs.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable frame to support the operating parts of the machine. Across this frame is properly o journaled the shaft B, by means of which motion is imparted to the several parts. At about the center of this shaft is properly keyed a broad pinion, C, Fig. 3, which engages with the crown-gear guide-wheels D, which in turn are properly journaled upon the vertical studs a, which rise from the frame A. The faces of these wheels D are provided with an annular groove, E, and recesses l), which, in the rotation of the wheels D, embrace the barb and present it to the hammer, as hereinafter set forth. Wheels G are mounted on bent arms secured to the frame A, so as to bear on the outer edges of the upper surfaces of the wheels D, to keep them always horizontal and keep them constantly in gear with the pinion 0.

Upon one end of the shaftis secured a proper pulley, F, by means of which and a belt the said shaft is driven from any proper power. Upon the opposite end of this shaft is secured a pinion, H, which, by a train of gear-wheels, I J K, imparts a rotary motion to the shaft L, to which is properly keyed a bevel-pinion, M, which in turn meshes with a similar pinion, N, which is properly secured upon a short hollow shaft, P, Fig. 4, properly journalcd in the riser 0, the center of such shaft]? being in line with the point where the two Wheels D come together. In the outer face of this bevel-pinion N is secured the divider B, said divider being constructed of two screw-plates, r, properly secured together, with a space between them, forming a hollow anger, as shown. The two plates 7' of the dividerRareinserted one partly within the other, as shown in Fig. 4E, and are secured together by studs r near their peripheries, so as to leave sufficient space between them for the passage of one barb at a time, and to form two ends for separating the barbs on the wire. Two guide-wires, c, are secured at one end of the frame A, and projectthrough the divider R and hollow shaft P back immediately over the Wheels D, and are secured to the two risers S. The wire upon which the barbs are to be placed passes from end to end of the machine, between the guide-wires 0, through the divider and hollow shaft, between the wheels D, and out between the risers S S, as will be more fully hereinafter set forth.

Upon the upper face of each of the wheels D are secured, preferably adjustably, three cams, d, which in the rotation of the wheels elevate the trip-rods 6, one end of each of which is pivoted to a block, h, secured to the studs a, while their outer ends come in contact with the rods T, which are pivotally secured to the frame, and raise their inner ends, which in turn come in contact with the yoke U, which carries the hammer V. In the continued rotation of the wheels D their respective cams pass from under the trip-rods, which releases the hammer from its elevated position, allowing it to fall upon the head of the double knife W, which is properly secured to the free ends of the springs X, which project forward from the top of the risers S, the depth of cutof such knife W being regulated by stop-blocks t upon the top of the girt Y, which secures the two upper ends of the vertical studs to together.

A represents trip-rods, which are actuated by the cams cl upon the wheels D, for the purpose of raising at stated intervals the stop bar or red B.

In practice the wire upon which the barbs are to be placed is preferably wound upon a spool and hung in a suitable frame at the front end of the machine, and the barbs O are strung upon this wire in asuitable number to provide the wire with barbs at certain distances apart its entire length. The end of the wire is then passed through the divider R and hollow shaft P,back to and between the wheels D, and thence back between the risers S, and is secured to another spool at the rear of the machine, both spools, if desired, being operated by belts from themachine in such a manner that it will be coiled upon one spool as fast as it is uncoiled from the other. Aswill be seen from the drawings, each of the wheels D is provided with six recesses for receiving the barbs, and with three cams for operating the trip-rods e and A, and'these three cams are so arranged as to raise the trip-rods e and A six timesateachrevolutionofthewheelsD. Motion now being imparted to the sh aft B, and through it to the operating parts of the machine, the wheels are caused to rotate, while the divider D picks up one of the barbs upon the wire at each half-revolution and passes it through the hollow shaft P, the wire and barb advancing together until the barb comes in contact with the stop-bar B, where it remains during the advancement of the wire through the machine until the stop-bar is raised by means of the trip A, the movements of which are timed so that the barb will advance and be embraced by the recesses b of the wheels D as they come opposite to each other. At this point the trips e are timed so that the hammer will be raised and allowed to drop upon the knife W, which is driven down by such impact upon the wire, forming, as the knife straddles the bar, a burr or spur, it, upon each side thereof, and in the continued operation of the machine the barbs will be distributed along the wire and secured between the spurs at equal distances apart, while the guide-rods c compel the barbs to advance to the divider and to the wheels D D in a vertical position.

What we claim as our invention is-- 1.
